Description

dehumidifier

[0001] The present disclosure relates to a dehumidifier, and more particularly, to a dehumidifier having a water block that absorbs heat energy generated during a dehumidification process.

[0002] A dehumidifier is a device that removes moisture from indoor air. It condenses moisture contained in the air and collects the condensed water. Users can remove the tank containing the collected condensed water from the dehumidifier and drain it.

[0003] Condensing moisture in indoor air requires a cooling device that maintains a temperature lower than the indoor air temperature. However, dehumidifiers generate a large amount of heat in return for maintaining a low temperature. For example, in a refrigeration cycle, the evaporator maintains a low temperature and condenses moisture in the air, while the condenser releases a large amount of heat to the outside. Furthermore, in thermoelectric devices, to maintain a low temperature in the low-temperature region, a large amount of heat is generated in the high-temperature region.

[0004] A 'small dehumidifier' disclosed in Korean Patent Publication No. 10-2020-0130613 comprises: a case having an intake port and an exhaust port; a cooling plate disposed inside the case to cool intake air and condense water vapor; a heat sink disposed inside the case to reheat air cooled by the cooling plate; a Peltier element positioned between the cooling plate and the heat sink to absorb heat from the cooling plate and transfer the absorbed heat to the heat sink; a fan to form an airflow; and a condensate reservoir to store condensate condensed by the cooling plate.

[0005] The conventional dehumidifier described above cools air on a cooling plate, removing moisture from the air. The cooled air is then reheated on a heat sink and supplied to the indoor space. Therefore, it suffers from the problem of high-temperature air being discharged into the indoor space. This high-temperature air can cause discomfort to occupants.

[0006] In addition, the conventional dehumidifier has a problem of rapidly increasing the internal temperature when the dehumidifier is used in a narrow space such as a closet.

[0007] In addition, the conventional dehumidifier has a problem in that it cannot control the amount of heat generated by itself.

[0008] In addition, the conventional dehumidifier has a problem in that the dehumidifying performance of the dehumidifier is reduced because it discharges high-temperature air to the surrounding area.

[0028] The above suction port is formed on the upper surface of the case, so that the suction airflow can have less interference with structures located in the surrounding space of the dehumidifier.

[0029] The above cooling module is arranged below the intake port, so that airflow drawn in through the intake port can pass through the cooling module while descending.

[0036] The above euro guide may include a middle wall that divides an inlet passage located at the lower side of the suction port and an outlet passage located at the lower side of the discharge port.

[0037] Specific details of other embodiments are included in the detailed description and drawings.

[0038] According to at least one of the embodiments of the present disclosure, a dehumidifier can be provided that minimizes the amount of heat discharged to the outside by having a water block that absorbs heat generated from a cooling module.

[0039] According to at least one embodiment of the present disclosure, heat generated from the cooling module is absorbed by the water block, thereby providing a dehumidifier that minimizes the amount of heat discharged to the outside. Furthermore, the temperature rise in the surrounding space where the dehumidifier is placed can be reduced.

[0040] According to at least one of the embodiments of the present disclosure, a dehumidifier capable of self-heating control can be provided, comprising a water block that absorbs heat generated from a cooling module, and a lower tank that supplies cooled water to the water block and recovers heated water.

[0041] According to at least one embodiment of the present disclosure, the lower tank can be spaced apart from the cooling module to minimize the amount of thermal energy transferred from the lower tank to the cooling module. This can reduce the dehumidification performance of the cooling module deterioration due to temperature increase.

[0042] According to at least one embodiment of the present disclosure, a middle tank is positioned between the lower tank and the cooling module, such that the middle tank can reduce heat transfer between the lower tank and the cooling module. For example, the middle tank, which stores condensate, can absorb heat transferred from the lower tank to the water block. In other words, the middle tank can perform an insulating function.

[0043] According to at least one of the embodiments of the present disclosure, a compact dehumidifier can be provided by a cooling block in contact with a low-temperature portion of a thermoelectric element and a water block in contact with a high-temperature portion of the thermoelectric element. In addition, a portable dehumidifier can be provided.

[0044] According to at least one embodiment of the present disclosure, the lower tank can be separated from the cooling block to minimize the amount of thermal energy transferred from the lower tank to the cooling block. This can reduce the dehumidification performance of the cooling module deterioration due to temperature increase.

[0045] According to at least one embodiment of the present disclosure, the lower tank can be separated from the water block to minimize the amount of thermal energy transferred from the lower tank to the water block. This can reduce the degradation of the heat absorption performance of the water block that absorbs heat emitted from the thermoelectric element.

[0046] According to at least one embodiment of the present disclosure, a middle tank is disposed between the lower tank and the water block, such that the middle tank can reduce heat transfer between the lower tank and the water block. For example, the middle tank, which stores condensate, can absorb heat transferred from the lower tank to the water block. In other words, the middle tank can perform an insulating function. This can reduce the degradation of the heat absorption performance of the water block that absorbs heat emitted from the thermoelectric element.

[0047] According to at least one of the embodiments of the present disclosure, the cooling module is positioned below the intake port, and the middle tank is positioned below the cooling module, so that the airflow introduced through the intake port can guide the condensate formed in the cooling module to the middle tank located below while descending. As a result, the condensate collection performance can be improved.

[0048] According to at least one embodiment of the present disclosure, the amount of airflow flowing within the case into the water collection port of the middle tank can be reduced due to the middle cap covering the water collection port of the middle tank. This can reduce flow disturbance and flow loss within the dehumidifier.

[0049] According to at least one embodiment of the present disclosure, the suction port is formed on the upper surface of the case, such that the suction port can be separated from structures arranged around the case. This reduces the problem of the suction port being blocked by surrounding structures. Furthermore, the problem of the airflow toward the suction port being obstructed by surrounding structures can be reduced.

[0050] According to at least one embodiment of the present disclosure, the outlet is formed on the upper surface of the case, and the outlet can be separated from structures arranged around the case. This can reduce the problem of the outlet being blocked by surrounding structures. Furthermore, the problem of the airflow being obstructed through the outlet due to surrounding structures can be reduced.

[0051] According to at least one of the embodiments of the present disclosure, the flow efficiency inside the case can be improved due to a guide wall extending from the intake port and guiding air drawn in through the intake port to the cooling module.

[0052] According to at least one embodiment of the present disclosure, a guide wall is positioned between the intake port and the water block to minimize the airflow drawn in through the intake port from approaching the water block. This reduces the phenomenon of the intake airflow contacting the water block and causing a temperature increase. This can improve the dehumidification performance of the cooling module.

[0053] According to at least one embodiment of the present disclosure, a partition wall extending downward from a guide wall and positioned between a cooling block and a water block is included, wherein the partition wall guides the inflow airflow to approach the cooling block and minimizes the approach to the water block. This reduces the phenomenon of the inflow airflow contacting the water block and causing a temperature increase. This improves the dehumidification performance of the cooling module.

[0054] According to at least one embodiment of the present disclosure, the flow efficiency within the case can be improved due to the middle wall that divides the inlet and outlet passages. Furthermore, the partition wall can improve the dehumidification performance of the dehumidification module by separating non-dehumidified air from dehumidified air.

[0110]

[0111] Referring to Fig. 3, the internal structure of the dehumidifier (1) is described.

[0112] The dehumidifier (1) may include a thermoelectric element (64). The thermoelectric element (64) may be a Peltier effect element. The thermoelectric element (64) may include a hot side that releases heat to the surroundings and a cool side that cools the surroundings. For example, the thermoelectric element (64) may include a low-temperature side formed on one side and a high-temperature side formed on the other side. The low-temperature side and the high-temperature side may be formed on opposite sides. Conversely, the thermoelectric element (64) may have a high-temperature side formed on one side and a cool side formed on the other side depending on conditions.

[0113] A thermoelectric element (64) may be placed inside the case (60). A cooling module (61) may include a thermoelectric element (64). The cooling module (61) may cool the surroundings using the low-temperature portion of the thermoelectric element (64). The cooling module (61) may condense moisture in the air using the low-temperature portion of the thermoelectric element (64). Moisture in the air may be condensed when passing through the low-temperature portion of the thermoelectric element (64).

[0114] The cooling module (61) may include a cooling block (62) that contacts a thermoelectric element (64). The cooling block (62) may contact one surface of the thermoelectric element (64).

The cooling block (62) may be cooled by the low-temperature portion of the thermoelectric element (64). The cooling block (62) may maintain a low temperature through the thermoelectric element (64).

[0115] The cooling block (62) may be a heat sink. The cooling block (62) may conduct heat generated by the thermoelectric element (64) to the outside.

The cooling block (62) may be formed of a metal material. The cooling block (62) may be formed of a material with high thermal conductivity. For example, the cooling block (62) may be formed of aluminum.

[0116] The cooling block (62) in contact with the low-temperature portion of the thermoelectric element (64) can be kept cold. Moisture contained in the air can condense as it passes through the cooling block (62). As a result, condensation can form on the surface of the cooling block (62).

[0117] The dehumidifier (1) may include a water block (66) that contacts a thermoelectric element (64). The water block (66) may contact the other surface of the thermoelectric element (64).

Through this, the water block (66) can absorb heat generated from the thermoelectric element (64). That is, the water block (66) can cool the thermoelectric element (64).

[0153] A flow space (660) through which cooling water flows may be formed inside the water block (66). The cooling water may circulate between the water block (66) and the lower tank (20). The cooling water may circulate between the lower tank (20) and the water block (66) through a pipe (90) connected to the water block (66). Through this, the cooling water filled inside the water block (66) may absorb heat generated from a high temperature part of the thermoelectric element. The cooling water that has absorbed the heat may flow from the water block (66) to the lower tank (20).

[0154]

[0155] Referring to Fig. 7, the internal layout of the dehumidifier (1) is described.

[0156] A fan (83) may be placed in the intake port (820). The fan (83) may form an airflow that flows into the intake port (820). For example, a pair of fans (83) may be placed in a pair of intake ports (820) to form an airflow that flows into the interior of the case (60) and descends.

[0157] The airflow drawn in through the intake port (820) can pass through the cooling block (62). The cooling block (62) can be located below the intake port (820). For example, the descending airflow drawn in through the intake port (820) can pass through the cooling block (62) located below. The cooling block (62) can cool the passing airflow. During this process, moisture contained in the airflow can condense upon contact with the cooling block (62). Condensate can form on the surface of the cooling block (62).

[0162] The water block (66) may be positioned below the suction port (820). The guide wall (72) may be positioned between the water block (66) and the suction port (820). The guide wall (72) may close the space between the water block (66) and the suction port (820). In this way, the guide wall (72) may prevent the airflow introduced through the suction port (820) from approaching the water block (66). That is, the guide wall (72) may prevent the introduced airflow from flowing to the water block (66). The water block (66) may be spaced apart from the guide passage (700). The water block (66) may be isolated from the guide passage (700).

[0163] A partition wall (76) may be positioned between the cooling block (62) and the water block (66). The partition wall (76) may close the space between the cooling block (62) and the water block (66). In this way, the partition wall (76) may prevent the airflow passing through the cooling block (62) from approaching the water block (66). That is, the water block (66) may be spaced apart from the partition flow path (704). The water block (66) may be isolated from the partition flow path (704).

The pump (98) may be located between the water supply pipe (92) and the cooling pipe (94). Through this, the pump (98) may suck the cooling water stored in the lower tank (20) into the water supply pipe (92).

[0165] Cooling water flowing through the water supply pipe (92) can be introduced into the cooling pipe (94). The cooling water introduced into the cooling pipe (94) can be supplied to the water block (66).

[0166] The cooling pipe (94) may be arranged on a flow path inside the case (60). The cooling pipe (94) may be arranged on the inlet flow path (832). The cooling pipe (94) may be arranged on the outlet flow path (834). The cooling pipe (94) may be arranged downstream of the cooling block (62). The cooling pipe (94) may be arranged on the lower side of the cooling block (62). The cooling pipe (94) may be spaced downward from the cooling block (62). The cooling pipe (94) may cross between the cooling block (62) and the middle tank (40). The cooling pipe (94) may be arranged on the upper side of the middle tank (40). The cooling pipe (94) may be spaced upward from the middle tank (40).

[0167] The cooling tube (94) may include an outflow cooling tube (942) disposed in the outflow passage (834). The outflow cooling tube (942) may form an upstream portion of the cooling tube (94). The outflow cooling tube (942) may be connected to a pump (98). The outflow cooling tube (942) may be disposed above the middle tank (40). The outflow cooling tube (942) may be spaced upward from the middle tank (40). Through this, the cooling water flowing through the outflow cooling tube (942) may be cooled by the air current flowing through the outflow passage (834).

[0168] The cooling tube (94) may include an inlet cooling tube (see FIG. 8, 944) disposed in the inlet passage (832). The inlet cooling tube (944) may extend from the outlet cooling tube (942).

[0169] The cooling pipe (94) may include a bending pipe (946) extending from the inlet cooling pipe (944). The bending pipe (946) may be connected to the water block (66). The bending pipe (946) may connect between the inlet cooling pipe (944) and the water block (66). The bending pipe (946) may pass through the lower side of the side wall (74). The bending pipe (946) may be connected to the water block (66) by bypassing the flow guide (70). For example, the bending pipe (946) extending from the inlet cooling pipe (944) disposed in front of the flow guide (70) may bypass the flow guide (70) and be connected to the water block (66) disposed in the rear of the flow guide (70).

[0170] The middle wall (73) can partition the inlet passage (832) and the outlet passage (834). The middle wall (73) can be positioned between the inlet passage (832) and the outlet passage (834). For example, the inlet passage (832) can be positioned below the intake port (820), the outlet passage (834) can be positioned below the discharge port (840), and the partition wall (76) can be positioned below the top cover (80) between the inlet passage (832) and the outlet passage (834).

[0171] The middle wall (73) may be located on the upper side of the middle tank (40). The middle wall (73) may be spaced upward from the middle tank (40).

[0172] The airflow passing through the cooling block (62) can pass through the gap between the middle wall (73) and the middle tank (40). The gap between the middle wall (73) and the middle tank (40) can connect the inlet passage (832) and the outlet passage (834). For example, the descending airflow passing through the cooling block (62) can hit the middle tank (40) and flow into the gap between the middle wall (73) and the middle tank (40). At this time, the middle cap (44) arranged in the collection guide (42) can reduce the descending airflow from flowing into the middle tank (40) through the collection hole. Through this, the flow loss of the airflow can be reduced.

[0173] The flow guide may include an extension wall (78) forming an outflow path (834). The extension wall (78) may extend from the middle wall (73).

For example, the inlet cooling tube (944) may be formed of silicone. The inlet cooling tube (944) may be formed of a material with high thermal conductivity.

[0179] The cooled airflow passing through the cooling block (62) can cool the cooling tube (94). The cold airflow passing through the cooling block (62) can cool the cooling water flowing through the cooling tube (94). As a result, the temperature of the cooling water flowing through the cooling tube (94) can be lowered.

The condensate formed on the surface of the cooling tube (94) may evaporate when it encounters a cooling air current. Accordingly, during the process of evaporation of the condensate, heat is taken from the cooling water flowing inside the cooling tube (94), so that the cooling water can be further cooled. The remaining condensate that does not evaporate may fall from the cooling tube (94) to the middle tank (40).
